Young people’s projects for a sustainable future

Post Syndicated from Rosa Brown original https://www.raspberrypi.org/blog/young-peoples-projects-for-a-sustainable-future/

This post has been adapted from issue 19 of Hello World magazine, which explored the interaction between technology and sustainability.

We may have had the Coolest Projects livestream, but we are still in awe of the 2092 projects that young people sent in for this year’s online technology showcase! To continue the Coolest Projects Global 2022 celebrations, we’re shining a light on some of the participants and the topics that inspired their projects.

In this year’s showcase, the themes of sustainability and the environment were extremely popular. We received over 300 projects related to the environment from young people all over the world. Games, apps, websites, hardware — we’ve seen so many creative projects that demonstrate how important the environment is to young people. 

Here are some of these projects and a glimpse into how kids and teens across the world are using technology to look after their environment.      

Using tech to make one simple change 

Has anyone ever told you that a small change can lead to a big impact? Check out these two Coolest Projects entries that put this idea into practice with clever inventions to make positive changes to the environment.

Arik (15) from the UK wanted to make something to reduce the waste he noticed at home. Whenever lots of people visited Arik’s house, getting the right drink for everyone was a challenge and often resulted in wasted, spilled drinks. This problem was the inspiration behind Arik’s ‘Liquid Dispenser’ project, which can hold two litres of any desired liquid and has an outer body made from reused cardboard. As Arik says, “You don’t need a plastic bottle, you just need a cup!”

Amrit (13), Kingston (12), and Henry (12) from Canada were also inspired to make a project to reduce waste. ‘Eco Light’ is a light that automatically turns off when someone leaves their house to avoid wasted electricity. For the project, the team used a micro:bit to detect the signal strength and decide whether the LED should be on (if someone is in the house) or off (if the house is empty).

“We wanted to create something that hopefully would create a meaningful impact on the world.”

Projects for local and global positive change 

We love to see young people invent things to have positive changes in the community, on a local and global level.

This year, Sashrika (11) from the US shared her ‘Gas Leak Detector’ project, which she designed to help people who heat their homes with diesel. On the east coast of America, many people store their gas tanks in the basement. This means they may not realise if the gas is leaking. To solve this problem, Sashrika has combined programming with physical computing to make a device that can detect if there is a gas leak and send a notification to your phone.

Sashrika’s project has the power to help lots of people and she has even thought about how she would make more changes to her project in the name of sustainability: 

“I would probably add a solar panel because there are lots of houses that have outdoor oil tanks. Solar panel[s] will reduce electricity consumption and reduce CO2 emission[s].”

Amr in Syria was also thinking about renewable energy sources when he created his own ‘Smart Wind Turbine’.  

The ‘Smart Wind Turbine’ is connected to a micro:bit to measure the electricity generated by a fan. Amr conducted tests that recorded that more electricity was generated when the turbine faced in the direction of the wind. So Amr made a wind vane to determine the wind’s direction and added another micro:bit to communicate the results to the turbine. 

Creating projects for the future  

We’ve also seen projects created by young people to make the world a better place for future generations. 

Naira and Rhythm from India have designed houses that are suited for people and the planet. They carried out a survey and from their results they created the ‘Net Zero Home’. Naira and Rhythm’s project offers an idea for homes that are comfortable for people of all abilities and ages, while also being sustainable.

“Our future cities will require a lot of homes, this means we will require a lot of materials, energy, water and we will also produce a lot of waste. So we have designed this net zero home as a solution.”

Naira and Rhythm

Andrea (9) and Yuliana (10) from the US have also made something to benefit future generations. The ‘Bee Counter’ project uses sensors and a micro:bit to record bees’ activity around a hive. Through monitoring the bees, the team hope they can see (and then fix) any problems with the hive. Andrea and Yuliana want to maintain the bees’ home to help them continue to have a positive influence on our environment.

Knowledge is power: projects to educate and inspire 

Some young creators use Coolest Projects as an opportunity to educate and inspire people to make environmental changes in their own lives.

Sabrina (13) from the UK created her own website, ‘A Guide to Climate Change’. It includes images, text, graphics of the Earth’s temperature change, and suggestions for people to minimise their waste.  Sabrina also received the Broadcom Coding with Commitment award for using her skills to provide vital information about the effects of climate change.

Kushal (12) from India wanted to use tech to encourage people to help save the environment. Kushal had no experience of app development before making his ‘Green Steps’ app. He says, “I have created a mobile app to connect like-minded people who want to do something about [the] environment.”

Kushal’s app helps people to upload and save pictures, like content from other users, and access helpful resources

These projects are just some of the incredible ideas we’ve seen young people enter for Coolest Projects this year. It’s clear from the projects submitted that the context of the environment and protecting our planet resonates with so many students, summarised by Sabrina, “Some of us don’t understand how important the earth is to us. And I hope we don’t have to wait until it is gone to realise.” 

Check out the Coolest Projects showcase for even more projects about the environment, alongside other topics that have inspired young creators.

Computing and sustainability in your classroom | Hello World #19

Post Syndicated from Gemma Coleman original https://www.raspberrypi.org/blog/computing-sustainability-classroom-hello-world-19/

Issue 19 of our free magazine Hello World, written by and for the computing education community, focuses on the interaction between sustainability and computing, from how we can interact with technology responsibly, to its potential to mitigate climate change.

Cover of issue 19 of Hello World magazine.

To give you a taste of this brand-new issue, here is primary school teacher Peter Gaynord’s article about his experience of using an environmental case study to develop a cross-curricular physical computing unit that gives his learners a real-life context.

Real-life problem solving

The prospect of developing your own unit of work from scratch can feel very daunting. With the number of free resources available, it begs the question, why do it? Firstly, it gives you the opportunity to deliver computing that is interwoven with the rest of your curriculum. It also naturally lends itself to a constructionist approach to learning through meaningful engagement with real-world problem-solving. In this article, I am going to share my experience of developing a ten-lesson unit of physical computing for students aged nine to ten that is linked to the more general topic of the environment.

To engage children in the process of problem-solving, it is important that the problem is presented as a real and meaningful one. To introduce the topic of the environment, we showed pupils a video of the Panama Canal, including information about the staggering amount of CO2 that is saved by ships taking this route instead of the alternative, longer routes that use more fuel. However, we explained that because of the special geographical features, a moving bridge needed to be constructed over the canal. The students’ challenge was first to design a solution to the problem, and then to make a working model.

One bridge model from Peter’s class.

The model would use physical computing as part of the solution to the problem. The children would program a single-geared motor using a Crumble microcontroller to slowly lift and lower the bridge by the desired amount. We decided to issue a warning to drivers that the road bridge was about to close using a Sparkle, a programmable LED. Ultimately, the raising and lowering of the bridge would happen automatically when a ship approached. For this purpose, we would use an ultrasonic sensor to detect the presence of the ship.

Building the required skills

To develop the skills required to use the Crumble microcontroller, we led some discrete computing lessons based largely on the Teach Computing Curriculum’s ‘Programming A — Selection in physical computing’ unit. In these lessons, the children developed the skill of sensing and responding differently to conditions using the selection programming construct. They learnt this key concept alongside controlling and connecting the motor, the Sparkle, and the ultrasonic sensor.

Physical computing allows learners to get hands-on.

For students to succeed, we also had to teach them skills from other subjects, and consider at what stage it would be most useful to introduce them. For example, before asking children to document their designs, we first needed to teach the design technology (DT) objectives for communicating ideas through sketches. Most other DT objectives that covered the practical skills to make a model were interwoven as the project progressed. At the end of the project, we guided the children through how to evaluate their design ideas and reflect on the process of model making. Before pupils designed their solutions, we also had to introduce some science for them to apply to their designs. We covered increasing forces using levers, pulleys, and gears, as well as the greenhouse effect and how burning fossil fuels contributes to global warming.

Another bridge model made in Peter’s class.

It is very important not to specify a solution for students at the beginning, otherwise the whole project becomes craft instead of problem-solving. However, it is important to spend some time thinking about any practical aspects of the model building that may need extra scaffolding. Experience suggested that it was important to limit the scale of the children’s models. We did this by showing them a completed central bridge span and later, guiding the building of this component so that all bridges had the same scale. It also turned out to be very important that the children were limited in their model building to using one single-geared motor. This would ensure that all children engaged with actively thinking about how to utilise the lever and pulley system to increase force, instead of relying on using more motors to lift the bridge.

Green information technology and classroom discussions

Post Syndicated from Gemma Coleman original https://www.raspberrypi.org/blog/green-information-technology-climate-change-data-centre-e-waste-hello-world/

The global IT industry generates as much CO2 as the aviation industry. In Hello World issue 17, we learn about the hidden impact of our IT use and the changes we can make from Beverly Clarke, national community manager for Computing at School and author of Computer Science Teacher: Insight Into the Computing Classroom.

With the onset of the pandemic, the world seemed to shut down. Flights were grounded, fewer people were commuting, and companies and individuals increased their use of technology for work and communication. On the surface, this seemed like a positive time for the environment. However, I soon found myself wondering about the impact that this increased use of technology would have on our planet, in particular the increases in energy consumption and e-waste. This is a major social, moral, and ethical issue that is hiding in plain sight — green IT is big news.

This is a major social, moral, and ethical issue that is hiding in plain sight — green IT is big news.

Energy and data centres

Thinking that online is always better for the planet is not always as straightforward as it seems. If we choose to meet via conference call rather than travelling to a meeting, there are hidden environmental impacts to consider. If there are 50 people on a call from across the globe, all of the data generated is being routed around the world through data centres, and a lot of energy is being used. If all of those people are also using video, that is even more energy than audio only.

Data centres consume a lot of energy — and how is that energy generated?

Not only is the amount of energy being used a concern, but we must also ask ourselves how these data centres are being powered. Is the energy they are using coming from a renewable source? If not, we may be replacing one environmental problem with another.

What about other areas of our lives, such as taking photos or filming videos? These two activities have probably increased as we have been separated from family and friends. They use energy, especially when the image or video is then shared with others around the world and consequently routed through data centres. A large amount of energy is being used, and more is used the further the image travels.

Not only is the amount of energy being used a concern, but we must also ask ourselves how these data centres are being powered.

Similarly, consider social media and the number of posts individuals and companies make on a daily basis. All of these are travelling through data centres and using energy, yet for the most part this is not visible to the user.

E-waste

E-waste is another green IT issue, and one that will only get worse as we rely on electronic devices more. As well as the potential eyesore of mountains of e-waste, there is also the impact upon the planet of mining the precious metals used in these electronics, such as gold, copper, aluminium, and steel.

In their marketing, device manufacturers and mobile network carriers make us see the phones we currently own in a negative light so that we feel the need to upgrade to the newest model.

The processes used to mine these metals lead to pollution, and we should also consider that some of the precious metals used in our devices could run out, as there is not an endless supply in the Earth’s surface.

It is also problematic that a lot of e-waste is sent to developing countries with limited recycling plants […].

It is also problematic that a lot of e-waste is sent to developing countries with limited recycling plants, and so much of the e-waste ends up in landfill. This can lead to toxic substances being leaked into the Earth’s surface.

First steps towards action

With my reflective hat on, I started to think about discussions we as teachers could have with pupils around this topic, and came up with the following:

  • Help learners to talk about the cloud and where it is located. We can remind them that the cloud is a physical entity. Show them images of data centres to help make this real, and allow them to appreciate where the data we generate every day goes.
  • Ask learners how many photos and videos they have on their devices, and where they think those items are stored. This can be extended to a year group or whole-school exercise so they can really appreciate the sheer amount of data being used and sent across the cloud, and how data centres fit with that energy consumption. I did this activity and found that I had 7163 photos and 304 videos on my phone — that’s using a lot of energy!

Helping young people gain an understanding of the impact of our use of electronic devices is an important action you can take.
  • Ask learners to research any local data centres and find out how many data centres there are in the world. You could then develop this into a discussion, including language related to data centres such as sensors, storage devices, cabling, and infrastructure. This helps learners to connect the theory to real-world examples.
  • Ask learners to reflect upon how many devices they use that are connected to the Internet of Things.
  • Consider for ourselves and ask parents, family, and friends how our online usage has changed since before the pandemic.
  • Consider what happens to electronic devices when they are thrown away and become e-waste. Where does it all go? What is the effect of e-waste on communities and countries?

Tips for greener IT

UK-based educators can watch a recent episode of TV programme Dispatches that investigates the carbon footprint of the IT industry. You can add the following tips from the programme to your discussions:

  • Turn off electronic devices when not in use
  • Use audio only when on online calls
  • Dispose of your old devices responsibly
  • Look at company websites and see what their commitment is to green IT, and consider whether we should support companies whose commitment to the planet is poor
  • Use WiFi instead of 3G/4G/5G, as it uses less energy

These lists are not exhaustive, but provide a good starting point for discussions with learners. We should all play our small part in ensuring that we #RestoreOurEarth — this year’s Earth Day theme — and having an awareness and understanding of the impact of our use of electronic devices is part of the way forward.

Some resources on green IT — do you have others?

What about you? In the comments below, share your thoughts, tips, and resources on green IT and how we can bring awareness of it to our learners and young people at home.

5750 Scottish children code to raise awareness of climate change with Code Club

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/cop26-5750-school-children-scotland-coding-climate-change-code-club/

This month, the team behind our Code Club programme supported nearly 6000 children across Scotland to “code against climate change” during the United Nations Climate Change Conference (COP26) in Glasgow.

“The scale of what we have achieved is outstanding. We have supported over 5750 young learners to code projects that are both engaging and meaningful to their conversations on climate.”

Louise Foreman, Education Scotland (Digital Skills team)

Creative coding to raise awareness of environmental issues

Working with teams from Education Scotland, and with e-Sgoil, our Code Club team hosted two live online code-along events that saw learners from 235 schools across Scotland come together to code and learn about protecting the environment.

“This type of event at this scale would not have been possible before the pandemic. Now joining and learning through live online events is quite normal, thanks to platforms like e-Sgoil’s DYW Live. That said, the success of these code-alongs has been above even our wildest imaginations.”

Peter Murray, Education Scotland (Developing the Young Workforce team)

Classes of young people aged 8 to 14 across Scotland joined the live online code-along through the national GLOW platform and followed Lorna from our Code Club team through a step-by-step project guide to code creative projects with an environmental theme.

At our first session, for beginners, the coding newcomers explored the importance of pollinating insects for the environment. They first learned that a third of the food we eat depends on pollinators such as bees and butterflies, and that these insects are endangered by environmental crises.

Then the young coders celebrated pollinating insects by coding a garden scene filled with butterflies, based on our popular Butterfly garden project guide. This Scratch project introduces beginner coders to loops while they code their animations, and it allows them to get creative and customise the look of their projects. Above are still images of two example animations coded by the young learners.

The second Code Club code-along event was designed for more confident coders. First, learners were asked to consider the impact of plastic in our oceans and reflect on the recent news that around 26,000 tonnes of coronavirus-related plastic waste (such as masks and gloves) has already entered our oceans. To share this message, they then coded a game based on our Save the shark Scratch project guide. In this game, players help a shark swim through the ocean trying to avoid plastic waste, which is dangerous to its health.

Supporting young people’s future together

These two Scotland-wide code-along events for schools were made possible by the long-standing collaboration between Education Scotland and our Code Club team. Over the last five years, our shared mission to grow interest for coding and computer science among children across Scotland has helped Scottish teachers start hundreds of Code Clubs.

A school-age child's written feedback about Code Club: "it was really fun and I enjoyed learning about coding and all of the things i can do in Scratch. I will use Scratch more now."
The school children who participated in the code-along sessions enjoyed themselves a lot, as shown by this note from one of them.

“The code-alongs were the perfect celebration of all the brilliant work we have done together over the years. What better way to demonstrate the importance of computing science to young people than to show them that not only can they use those skills on something important like climate change, but they are also in great company with thousands of other children across Scotland. I am excited about the future.”

Kirsty McFaul, Education Scotland (Technologies team)

Join thousands of teachers around the world who run Code Clubs

We also want to give kudos to the teachers of the 235 schools who helped their learners participate in this Code Club code-along. Thanks to your skills in supporting your learners to participate in online sessions — skills hard-won during school closures — over 5000 young people have been inspired about coding and protecting the planet we all share.

Teachers around the world run Code Clubs for their learners, with the help of our free Code Club resources and support. Find out more about starting a Code Club at your school at www.codeclub.org.

Digital making projects about protecting our planet

Post Syndicated from Emma Posey original https://www.raspberrypi.org/blog/free-digital-making-projects-protecting-our-planet/

Explore our new free pathway of environmental digital making projects for young people! These new step-by-step projects teach learners Scratch coding and include real-world data — from data about the impact of deforestation on wildlife to sea turtle tracking information.

By following along with the digital making projects online, young people will discover how they can use technology to protect our planet, all while improving their computing skills.

The projects help young people affect change

In the projects, learners are introduced to 5 of the United Nations’ 17 Sustainable Development Goals (SDGs) with an environment focus:

  • Affordable and Clean Energy
  • Responsible Consumption and Production
  • Climate Action
  • Life Below Water
  • Life on Land

The first project in the new pathway is an animation about the UN’s five SDGs focused on the environment.

Technology, science, maths, geography, and design all play a part in the projects. Following along with the digital making projects, young people learn coding and computing skills while drawing on a range of data from across the world. In this way they will discover how computing can be harnessed to collect environmental data, to explore causes of environmental degradation, to see how humans influence the environment, and ultimately to mitigate negative effects.

Where does the real-world data come from?

To help us develop these environmental digital making projects, we reached out to a number of organisations with green credentials:

Inspiring young people about coding with real-world data

The digital making projects, created with 9- to 11-year-old learners in mind, support young people on a step-by-step pathway to develop their skills gradually. Using the block-based visual programming language Scratch, learners build on programming foundations such as sequencing, loops, variables, and selection. The project pathway is designed so that learners can apply what they learned in earlier projects when following along with later projects!

The final project in the pathway, ‘Turtle tracker’, uses real-world data of migrating sea turtles!

We’re really excited to help learners explore the relationship between technology and the environment with these new digital making projects. Connecting their learning to real-world scenarios not only allows young people to build their knowledge of computing, but also gives them the opportunity to affect change and make a difference to their world!

Discover the new digital making projects yourself!

With Green goals, learners create an animation to present the United Nations’ environment-focused Sustainable Development Goals.

Through Save the shark, young people explore sharks’ favourite food source (fish, not humans!), as well as the impact of plastic in the sea, which harms sharks in their natural ocean habitat.

Illustration of a shark with sunglasses

With the Tree life simulator project guide, learners create a project that shows the impact of land management and deforestation on trees, wildlife, and the environment.

Computers can be used to study wildlife in areas where it’s not practical to do so in person. In Count the creatures, learners create a wildlife camera using their computer’s camera and Scratch’s new video sensing extension!

Electricity is important. After all, it powers the computer that learners are using! In Electricity generation, learners input real data about the type and amount of natural resources countries across the world use to generate electricity, and they then compare the results using an animated data visualisation.

Understanding the movements of endangered turtles helps to protect these wonderful animals. In this new Turtle tracker project, learners use tracking data from real-life turtles to map their movements off the coast of West Africa.

Code along wherever you are!

All of our projects are free to access online at any time and include step-by-step instructions. They can be undertaken in a club, classroom, or at home. Young people can share the project they create with their peers, friends, family, and the wider Scratch community.

Visit the Protect our planet pathway to experience the projects yourself.
